Problem
Nowadays, it is challenging to find a good homemade sandwich with fresh ingredients combined with a great overall delivery experience.
Solution
Monsieur Sandwich is a mobile app that offers fresh homemade sandwiches made with qualitative and local products, by delivery or to go, for an affordable price establishing a “dark bakery” concept. A Dark Bakery is a dark kitchen that specializes in bakeries. This operational model allows Monsieur Sandwich to propose high-quality bakeries and sandwiches at a low price compared to the market.
Monsieur Sandwich's value proposition is being delivered to users through Monsieur Sandwich's mobile native application. During our research and design process, facts and insights received allowed us to build seamless ad meaningful flows for our users with the following high-value capabilities:
Capability 1 : Ability to get your food delivered or taken away from the different Monsieur Sandwich Dark Bakery locations
Capability 2 : Ability to add or remove sandwiches' ingredients
Capability 3 : Ability to leave an extra note for the custom request (i.e, food allergies or intolerances)
Capability 4 : Ability to use different payment methods such as Credit Cards, Cash, PayPal...

Scenarios to be tested
Order a sandwich in delivery

Hypothesis to be tested
H1 : I believe that the choice for glass jars and containers
Will be clear and easy to make
For target users
Because they will have all the information about the two different options including their price
H2 : I believe that the choice concerning glass jars and containers
Will come at the right moment in the ordering process
For target users
Because it happens between the connection and payment step in the checkout process
H3 : I believe that selecting products before informing their address for delivery
Will make the product selection more simple and spontaneous
For target users
Because they won’t have to give information before selecting products
H4 : I believe that product detail pages
Will give all the information on products
For target users
Because it will inform about all ingredients, composition and possible allergens
H5 : I believe that the UI of product detail pages
Will create desire to purchase
For target users
Because large images catch more attention and is attractive
KPI
- KPI 1 : Number of users who succeed the mission
- KPI 2 : Number of users who didn't succeed the mission
- KPI 3 : End to end conversion rate > Number of users who succeed / divided by number of total users
Usability Plan

Results & Analysis
Based on the Atomic Research
Collection of participants' feedback to identify major pain points and themes.
Analysis of the data based on the Atomic methodology, extracting facts that lead to insights and then to improvement opportunities.
Overall, participants found that the UX flow was intuitive and straightforward. The main improvement opportunity participants raised was clarifying the connection between product selection and checkout, adding an intermediate step.

Participants used and enjoyed the different payment and connexion options offered to them in the app.
They also complimented the interface UI and appreciated the customisation options.
Design iteration
The usability test highlighted some pain points and improvement opportunities that I categorized and prioritized to refine the user flows.
Improvement point #1 : adding a transition between product selection and checkout
Addition of an intermediate step between product selection and the checkout process, providing users the choice to continue shopping or to go to checkout.
